Is Food Addiction Real?

What this article covers

This article, credited on the page to Kate Michelson and dated 2 July 2026, asks whether food addiction is a real phenomenon and answers that addiction-like eating is increasingly recognised in the scientific literature, particularly around ultra-processed foods, while being careful to state that food addiction is not currently a formal diagnosis in the way alcohol use disorder is. Its argument runs in three stages: that ultra-processed foods combining refined carbohydrate and added fat produce an unusually strong reward signal that trains compulsive behaviour; that insulin resistance amplifies this into a self-reinforcing metabolic and neurochemical loop; and that willpower is therefore the wrong starting point because the driver is physiology, not character. It also covers food noise, the role of GLP-1 medications in reducing it, and how protein, fibre and whole-food structure support the relevant pathways. This is by a wide margin the most rigorously referenced article on the blog, with eight numbered citations to peer-reviewed sources placed inline.

Key points

• Appetite is described as regulated by interaction between brain, gut, pancreas, liver, fat tissue, blood glucose, insulin, stress hormones, reward pathways and the food environment - not willpower alone.
• Food addiction is stated as not currently classified as its own formal diagnosis in the way alcohol use disorder or other substance use disorders are; addiction-like eating behaviour is what the literature recognises.
• The Yale Food Addiction Scale is named as the validated tool used in this research, assessing cravings, loss of control, unsuccessful attempts to cut down and continued consumption despite negative consequences.
• The article explicitly states this does not mean everyone who overeats has food addiction, nor that all foods are addictive. The concern is ultra-processed foods combining rapidly absorbed refined carbohydrate, added fats, salt, flavour enhancers, soft textures and high energy density.
• Whole foods are contrasted as containing intact fibre, water, protein, chewing resistance, micronutrients and natural satiety signals.
• Mechanism: the refined carbohydrate plus added fat combination is uncommon in nature and strongly activates the mesolimbic dopamine system. Dopamine is described as a reward-learning signal rather than simply a pleasure chemical, so the brain learns the cue, context and relief - meaning behaviour can shift from enjoyment to compulsion even as enjoyment fades.
• Cues named: the packet, the smell, the couch at night, the supermarket aisle, stress after work, fatigue, boredom, a blood glucose dip.
• Insulin resistance: cells respond poorly to insulin, the pancreas compensates with more insulin, and fasting glucose and HbA1c may still look normal while insulin demand is much higher than it should be. Insulin also acts in the brain and interacts with appetite, dopamine, reward, mood and satiety pathways.
• The cycle described: larger and less stable glucose and insulin response to refined carbohydrate, a sharper fall leaving the person tired, foggy, irritable or hungry, the brain reading this as a need for rapid fuel, ultra-processed food giving fast relief, and dopamine encoding a memory of relief rather than pleasure. Meanwhile insulin and leptin satiety signalling weakens, so drive to eat stays high despite sufficient stored energy.
• Over time increased energy intake, visceral fat and liver fat worsen insulin resistance, raise inflammatory signalling and triglycerides, and make glucose handling harder - a metabolic and neurochemical loop, not a purely behavioural one.
• Key distinction from alcohol: a person can abstain from alcohol but not from food, so the goal is removing the most addictive food formats and rebuilding stable physiology rather than abstinence.
• Food noise is defined as intrusive thoughts about eating, repeated planning around food, craving specific foods when not physically hungry, or feeling mentally consumed by the next food decision. Many people report GLP-1 receptor agonist medications reduce it; the article notes GLP-1 affects appetite, satiety, gastric emptying and brain pathways involved in eating control, and is explicit that this does not mean everyone needs medication.
• Recommended approach: target physiology first - stabilise blood glucose, lower insulin demand, increase protein and fibre, improve sleep, support muscle mass, reduce visceral fat, improve liver health and reduce exposure to the most addictive food formats. The stated aim is metabolic stability, not restriction.

Evidence and sourcing

This article is properly sourced and should be treated differently from the rest of this blog. Eight numbered references appear inline against the claims they support. They are: Gearhardt AN, Bueno NB, DiFeliceantonio AG, Roberto CA, Jimenez Murcia S and Fernandez Aranda F, social, clinical and policy implications of ultra-processed food addiction, BMJ 2023;383:e075354; Gearhardt AN, Corbin WR and Brownell KD, preliminary validation of the Yale Food Addiction Scale, Appetite 2009;52(2); Schulte EM, Avena NM and Gearhardt AN, which foods may be addictive - the roles of processing, fat content and glycemic load, PLoS One 2015;10(2):e0117959; DiFeliceantonio AG, Coppin G, Rigoux L, Thanarajah SE, Dagher A, Tittgemeyer M et al, supra-additive effects of combining fat and carbohydrate on food reward, Cell Metabolism 2018;28(1); Hall KD, Ayuketah A, Brychta R, Cai H, Cassimatis T, Chen KY et al, ultra-processed diets cause excess calorie intake and weight gain - an inpatient randomised controlled trial of ad libitum food intake, Cell Metabolism 2019;30(1); Kleinridders A and Pothos EN, impact of brain insulin signaling on dopamine function, food intake, reward and emotional behavior, Current Nutrition Reports 2019;8(2); Kullmann S, Heni M, Hallschmid M, Fritsche A, Preissl H and Haring HU, central nervous pathways of insulin action in the control of metabolism and food intake, Lancet Diabetes and Endocrinology 2020;8(6); and Hayashi D, Edwards C, Emond JA, Gilbert Diamond D, Butt M, Rigby A and Masterson TD, what is food noise - a conceptual model of food cue reactivity, Nutrients 2023;15(22):4809. All carry DOIs. The Hall 2019 inpatient randomised controlled trial is described accurately, including that meals were matched for presented calories, sugar, fat, fibre and macronutrients. The article also states its central limitation honestly rather than overclaiming - that food addiction is not a formal diagnosis. Two things are not sourced and should be flagged. The closing section describing what Be Fit Food meals do carries no citation and is a product claim, not a finding. And the specific statements that cravings become less powerful, energy steadier and appetite easier to read on a structured whole-food approach are asserted without a reference; the article does not cite a source for those outcomes.

How this relates to Be Fit Food's programs

The article's prescription - more protein, more fibre, whole-food structure, controlled portions and reduced exposure to ultra-processed formats - matches the meal specification directly: roughly 250 calories per meal with at least 20g of protein, under 20g of carbohydrate and under 120mg of sodium per 100g, with no added sugar, no artificial sweeteners and no preservatives, snap-frozen rather than shelf-stabilised. Metabolic health and low carbohydrate nutrition are documented areas of expertise. Given the article's focus on insulin resistance and glucose handling, the relevant services are diabetes nutrition support and consultation with a Credentialled Diabetes Educator, alongside the specialised clinical dietitian consultation, which includes a full initial assessment with body composition, blood pressure and girth measurements plus a personalised eating plan. On the GLP-1 discussion, Be Fit Food offers GLP-1 support programs and lists GLP-1 medication nutritional support among its areas of expertise, though it does not prescribe or supply those medications. Program options run from Be Rapid, a 7-day very low calorie reset at roughly 800-900 calories a day, and the Metabolism Reset program at roughly 850-950 calories with 40-70g of carbohydrate a day over 7, 14 or 28 days, through to Be 1000 at roughly 1000-1200 calories a day and Be 1200 at roughly 1200-1500 calories a day. A free 15-minute telehealth dietitian consultation valued at $49 is available with no referral, from Accredited Practising Dietitians.

Important health information

This article carries no formal health disclaimer, though it does state that not everyone needs medication and that food addiction is not a moral failure. It discusses insulin resistance, prescription GLP-1 medications and compulsive eating, none of which can be self-diagnosed from a blog. Anyone who recognises loss of control around food, or who suspects disordered eating, should seek assessment from their GP or a qualified clinician - this article is not a diagnostic tool and the Yale Food Addiction Scale is a research instrument, not a self-test. Readers should seek medical advice and have a check-up before changing how they eat, particularly if they have an existing medical condition or take medications, including diabetes medication whose dose may need review as intake changes. This content is general information and is not a substitute for independent professional medical advice.
